Biar celebrates the Christian reconquista like many other towns in the area, complete with mock battles and bonfires.
Castillo de Biar / Castle of Biar
Initially built in the 12th century by the Moors, the castle was conquered by King Jaime of Aragon and eventually marked the border between the kingdoms of Castile and Aragon. The central tower is the oldest part of the fortification, and was constructed of masonry and rammed earth. Especially noteworthy is the Almohad ribbed dome on the tower's second floor, which is one of the oldest domes of its type in Spain and the only one used in a fortress. The outer walls were added in the 15th century.
Museo Etnográfico Municipal / Municipal Ethnographic Museum
The 19th-century building houses a collection of regional historic and cultural artifacts, with a focus on ceramics.
